what is happening
How to balance reducing ARPU and manage growth:

Use USO: for Tower, power, W/L and OFC penetration

Bring in Virtual operator concept

Share Infrastructure

Operators wants to penetrate into rural areas

But People have less paying capacity (US$ 1-2 pm)

Thus Tariff is reducing

ARPU reducing

ITU-APT FDN of India

What is happening
what is infrastructure
ITU-APT FDN of IndiaWhat is infrastructure
  • Passive: Tower, Power, Land and Building etc.
  • Active
    • Switches: TDM and IP based
    • Transport network
      • OFC
      • Wireless: M/W, Satellite
    • Access network
      • Copper: Local loop
      • Fiber: L/D, Back Haul and FTTX
      • Wireless: BTS
    • Applications
    • Billing Systems
what to share
Example of tourism Industry

Bulk Ticketing, Pooled Pick-up drop, Bulk hotel booking, Group Sight seeing, Bulk lunch/Dinner

Thus to get maximum benefit: Why not Share/Pool

Access Network

Carrier/Transport network

Billing System

Applications

Infrastructure passive and active

Common interconnect

What to share?
interconnect issues
ITU-APT FDN of IndiaInterconnect Issues
  • Separate Network for Basic/Mobile (Voice) and for Data
  • Huge growth- Of the order of 15 Million mobile connections in a month in India
  • Increasing numbers of Application developers, no. of Oprs and their Traffic
  • Every Basic/Mobile operator have to have interconnection (or transit through) with each other and with many NLD and ILD oprs

results
ITU-APT FDN of IndiaResults
  • Sub-optimal utilization of resources
  • Inefficient handling of calls
  • High operational cost for managing inter operator connections
  • Inter opr/carrier billing problems
  • Complexity in settlement in Interconnect usage charges
  • Increase in CAPEX and OPEX
challenges
ITU-APT FDN of IndiaChallenges
  • Reduce High interconnection cost
  • Reduce Connection at different levels and at many places and Complex routing at every point
  • Reduce Huge requirement of ports and their cost
  • Physical provisions at different places causes delay and need more capacity
  • Resolution of billing disputes/court cases
what is the solution ngn ice
ITU-APT FDN of IndiaWhat is the Solution: NGN:ICE
  • Open and Fragmented Architecture
  • Best breed of products
  • Much Better Performance
  • Desired Quality of Service
  • Efficient inter working

‘And what not’

Thus NGN interconnect Exchanges can be best solution for inter connecting

ngn ip based interconnect exchange

advantages
ITU-APT FDN of IndiaAdvantages
  • Network planning fast and simple leads to reduction in cost and port charges
    • Simple network interconnection using Electrical/Optical, GE/STM interfaces
    • Reduction in number of links
    • Simplifies digit analysis for all inter operator and long distance calls from the switches connected to it
advantages contd
ITU-APT FDN of IndiaAdvantagescontd.
  • Fast provision/augmentation of PoIs as everybody knows physical location of IC
  • Integration of different service providers at one point
  • Help in quadruple (Voice, Video, Mobile TV and data) play in inter opr environment
  • Help in convergence of services, application and provisioning
  • Simplification in carrier selection function
advantages contd1
ITU-APT FDN of IndiaAdvantagescontd.
  • Integrated inter carrier billing/Clearing house
    • Less connection: less disputes: less court cases
    • Inter operator charging, based on GoS, Content and network elements used in interconnection
  • Intelligent network services
    • Easy provision in a multi opr and multi-service scenario
    • Content can be integrated at ICE and can be pooled to all the operators connected to it
  • Centralized LIS with artificial intelligence, Grid surveillance and encryption/decryption for voice and internet traffic
advantages contd2
ITU-APT FDN of IndiaAdvantagescontd.
  • Low latency and guaranteed QoS
  • Reduction in Capex and Opex
  • Down time can be reduced with resilient multiple node architecture
  • FMC and Femto cell concept in multi operator environment in case of intra roaming, thus saving in spectrum
implementation issues
ITU-APT FDN of IndiaImplementation issues
  • High upfront cost
  • Introduction of MG in case of TDM switches with E1/STM connectivity
  • Introduction of SBC in case of IP based switches with GE/MPLS connectivity
  • In domestic networks interconnect exchange (one or two depending on the business case) at charging area level and at Metro-city level
  • Duplicate connectivity or connectivity through Self healing rings
implementation issues contd
ITU-APT FDN of IndiaImplementation issues contd.
  • Migrating TDM switches to IP based architecture
  • Circumventing Security risks and ensuring hassle free LI
  • For few years existing Interconnect regime has to continue and in parallel NGN based interconnect Exchange
  • Duplication till full shift to IP/ICE but better in long run
  • UASL operator with centralized control of MG/SBC distributed in service area
implementation issues contd1
ITU-APT FDN of IndiaImplementation issues contd.
  • NLD/ILD operators may have centralized control at two places for geographical redundancy
  • By and by migration to NGN switches in the network and IP based interconnection
  • Integrating Voice, Video, Data & IPTV
  • Charging scenario will change but will be more versatile: Old Distance/Time based may be replaced by NGN based: QoS, B/W, Appln, Supplementary & VAS
who will do it
ITU-APT FDN of IndiaWho will do it?
  • Regulator and licencer: terms to be redefined with light touch approach
  • All stake holders to come to gather
  • By incumbent operator or by other or by a separate independent operator
  • Management by: To be decided by all stake holders

This is about ICE What about others?

so perhaps in future ngn will give
ITU-APT FDN of IndiaSo Perhaps in Future NGN will give
  • Separate access providers: DSL, Wi-Fi, WiMAX, FTTX, GSM, CDMA, 3G, 4G and xG etc
  • Separate: network provider with NGN core
  • Separate: long/short distance connectivity providers: by most Optimal Carrier Ethernet
  • Separate Infra: Tower, Power, BTS providers
  • Separate: Application Service providers
  • Strong Marketers with innovative ‘Tariff Products’ giving cheapest service to Public
  • Bring MVNO/ Virtual Operator concept AND

‘Specialized people will maintain different entities, conveniently and in the

Cheapest way’
